The invention discloses a vehicle fuel consumption prediction method and device and a computer program product, and the method comprises the steps: obtaining a vehicle inherent attribute parameter set, an environment parameter set and navigation path information containing altitude elevation; when the altitude of the destination is higher than the altitude of the current position of the vehicle, the maximum altitude difference is calculated based on the navigation path information, and the final climbing height is determined in combination with the altitude of the destination; according to the air density change corresponding to the final climbing height and the gradient feature of the navigation path, the incremental sliding resistance in the vehicle climbing process is calculated; inputting the vehicle inherent attribute parameter set and the environment parameter set into a pre-trained neural network model, and calculating the compensation oil consumption of the vehicle power system to the altitude change; calculating extra fuel consumption of the vehicle according to the incremental sliding resistance, the average speed of the vehicle in the navigation path, the compensation fuel consumption and the fuel consumption rate of an engine; and according to the current fuel consumption of the vehicle and the additional fuel consumption of the vehicle, corrected fuel consumption of the vehicle is calculated.

    本发明公开一种车辆油耗预测方法、装置及计算机程序产品,其中,方法包括:获取车辆固有属性参数集、环境参数集及包含海拔高程的导航路径信息;在目的地海拔高度高于车辆当前位置海拔高度时,基于所述导航路径信息计算最大海拔差,并结合目的地海拔高度确定最终爬升高度;根据所述最终爬升高度对应的空气密度变化及所述导航路径的坡度特征,计算车辆爬升过程中的增量滑行阻力;将所述车辆固有属性参数集、环境参数集输入预训练的神经网络模型,计算车辆动力系统对海拔变化的补偿油耗;根据所述增量滑行阻力、车辆在所述导航路径的平均车速、补偿油耗和发动机燃油消耗率,计算车辆额外油耗;根据车辆当前油耗和车辆额外油耗,计算得到车辆修正油耗。
